Synapse Analytics ADF Error - Failed to encrypt sub-resource payload or linked service credentials [Solved]

Issue: While trying to publish an HTTP or REST linked service connection from master to live, we get an error if it is going through a self hosted Integration run time to an on-premise network. 

Publishing error

Failed to encrypt sub-resource payload

and error is: Failed to encrypted linked service credentials on self-hosted IR 'selfHostedIR', reason is: NotFound, error message is: No online instance..

Cause: When you have a HTTP call that happens inside an on-premise network and you use a self hosted integration run time to connect to this, the first time the linked service is published it has to validate the connection and hence requires the Self Hosted IR to be up and running. 

Solution: The solution is to have the self hosted IR( Azure VM in our case ) up and running while trying to publish from master to live. This enables the validation of the linked service connection, this fixed it for us.

Please do let us know if this fix worked for you.
